+# This is a basic Fedora 20 spin designed to work in OpenStack and other
+# private cloud environments. It's configured with cloud-init so it will
+# take advantage of ec2-compatible metadata services for provisioning ssh
+# keys. Cloud-init creates a user account named "fedora" with passwordless
+# sudo access. The root password is empty and locked by default.
+#
+# Note that unlike the standard F20 install, this image has /tmp on disk
+# rather than in tmpfs, since memory is usually at a premium.
+#
+# This kickstart file is designed to be used with appliance-creator and
+# may need slight modification for use with actual anaconda or other tools.
+# We intend to target anaconda-in-a-vm style image building for F20.
